What is the benifit cofiguring DNS serve

DNS activity should be independent of domains, but I believe Win2000 uses DNS as an integral part of the hierarchical domain structure.

Having said that, the best reason for configuring DNS on a separate domain/workgroup is because DNS servers have historically been a target of hackers, and any machine that can be accessed from the internet shouldn't be part of any internal private network that you want to maintain any kind of security on.

Also, if you have 2 DNS servers, and each is in a different location, then if a router dies (taking access to that DNS server with it), then the clients will still be able to connect with the second DNS server.

MS had 2 DNS servers on the same subnet a few months ago, when everything went offline for them. If they were seperate, then there would have been no problem. One would have been down, the other would have been up, and working HARD.
